The artillery loop or harness loop is a knot with a loop on the bight for non-critical purposes. The artillery loop must have the loop loaded or it will slip and contract easily. It is an inferior knot to the alpine butterfly knot,^[3] possibly dangerously so, in that it can be yanked out of shape and turn into a running knot or noose.^[4]

2. ^ Entry #532 on page 87 of The Ashley Book of Knots shows a diagram of the alpine butterfly knot under the name harness loop. Ashley appears to have illustrated or named the incorrect knot in this case. The butterfly knot, under the name Lineman's Loop, is shown and discussed as a distinct and specific knot throughout the rest of the book.
